no, because according to him an atom is a tiny indestructable sphere with mass on it.
no, because according to him an atom is a tiny indestructable sphere with mass on it.
The electron cloud is not a model of the atomic nucleus. The electron cloud surrounds the atomic nucleus.
No, these particles were not known during the life of Dalton.
No.

density
a Bohr model is a diagram of an atom that describes the arrangement of the subatomic particles(electrons, neutrons, and protons) protons and neutrons are in the nucleus and the electrons in the electron shells.
The "Plum Pudding" Model of the atom was abandoned over a century ago, when it was shown, pretty conclusively, that all positive charge resides in a small nucleus at the center of each atom.
J.J. Thomson proposed that an atom consists of a mixture of positively charged protons and negatively charged electrons. In his model, the electrons can be thought of as tiny marbles suspended in a "pudding" made up of protons. Niels Bohr found this model to be incorrect, and instead described the atom more accurately as a sort of planetary configuration. In his model, electrons orbit the nucleus which consists of the protons. Bohr's model was backed up experimentally by Ernest Rutherford's work.

no, because according to him an atom is a tiny indestructable sphere with mass on it.
It was commonly described as a Solid sphere
The nucleus of a Helium atom contains two protons and two neutrons, protons and neutrons are measured in Daltons, and a Helium atom is about 4 Daltons
no, because according to him an atom is a tiny indestructable sphere with mass on it.
Thomsons model (plum pudding model of negatively charged particles in a positive soup) differed from Daltons model. Dalton hypothesised that atoms were indivisible, the word atom comes from the Greek atomos cannot be cut)
The mass number of an atom is the number of protons plus the number of neutrons in its nucleus. So an atom with 15 protons and 10 neutrons would have a mass number of 15 + 10 = 25.
A Dalton's model of atom doesn't exist. Dalton principles are not in agreement with the discovery of isotopes and nonstoichiometric compounds.
neutrons and protons
thomas discovered that the atom contained smaller particals called electrons
yes it did
